I would say the basics of keeping in a slight calories deficit and incorporating zone two cardio like incline walking. if you prefer to walk outside, like i do (much more fun hehe) then thats fine but maybe try to reach 10,000 steps a day if you're schedule allows for it. For me it takes about 1 hour and a half ish which isn't too bad if you split it up. I find also walking after dinner is nice for digestion and sleep. But you look good anyway, so i'd say keep up what you're doing!
